That tool is sweet and it sounds like youre kicking butt on these things. Great job!

My attempts to adapt a Medecoder to the 831b havent met much success. They shield a lot of the plug face with the body and force you cut a bunch of the scale tube away. Also tried basing the measurements off the lock body, but the cylinder likes to move around in there and mess that up. It seems like these scaled-groovegrabbers are the way to go for 831/833.
